Headaches at 17 weeks?

La

I’ll be 17 weeks tomorrow and have had a headache on the right side the last two days. It went away yesterday with 500 mg of Tylenol but I didn’t take Diclegis (anti nausea) medicine that I usually take because I didn’t want to mix the two. I have a headache again tonight. Checked my blood pressure and it was 106/53. Anyone else having headaches during the second trimester?
